通过交通调查发现规范中护栏的设计条件要求偏低 ,本文提出护栏高度与冲击力的简化计算方法 ,进而由数值方法对多种护栏进行分析 ,提出护栏的结构设计方法并进行了足尺实验的验证。
Through traffic investigation, we find that the design requirements of fence are low. This paper presents a simplified calculation method of fence height and impact force, and then analyzes a variety of fence by numerical method. It puts forward the structural design method of fence and conducts full-scale experiment verification.
